TLDR:

  • Zero with slash and one with serifs is the new default appearance, stylistic alts added (ss09, ss10) for original characters
  • Fixed metrics on composite glyphs
  • Improved sizing and spacing for the misc characters brought from standard Mona Sans
  • Small sample of coding ligatures

Inconsistent width value. The m020 layer has width 600 while m019 layer has width 618. All monospace glyphs should maintain consistent width across layers.
